Idle jumps and weird load noise

Hello all,
I just got 2011 35i with 180k miles few months ago. After installed spark plugs, ignition coils, idle tensioner, belt, pulleys. Car runs great for couple months. Now it start having either vacuum leak or something else. Car start up great when engine cold…drove for about 10 minutes when engine warm up…I heard load (really loud whistles noise toward near transmission (flywheel area). It go up and down along when I accelerate. The idle also go up and down as the same time. Its only happened when the engine getting hot (whistles noise and idle). Car still operate as normal when this happens. Is this a vacuum leak or turbo issue? Any input will be appropriate. Thank

After some researched…I think it leading to Crankcase Valve issue and possible Rear Main Seal (RMS) have a leak.
